[0002] Underground water, gas pipeline has been widely used in today's urban construction, but because underground water, gas pipeline is buried in the ground, under the condition of long time use, the problem of leakage will appear, when carrying out pipeline repair, need to utilize the detector to detect the pipeline, and then realize the discovery and repair of leakage point, avoid the influence of pipeline leakage on the normal life of nearby residents.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN216345480U discloses a self-made underground pipeline leakage point detector, which comprises a metal detection tube, a detection tip and a detection earpiece, one end of the metal detection tube is connected with the detection tip, and the other end of the metal detection tube is connected with the detection earpiece. By inserting the metal detection tube into the ground, the leakage sound of the underground pipeline is heard through the detection earpiece connected with the metal detection tube to determine the approximate position of the leakage point. The structure is simple and convenient to use. Compared with excavating a pipe trench, no additional detection cost and construction cost such as backfilling soil after excavation is generated. While rapidly detecting the leakage point, the leakage detection time and cost are effectively reduced.

[0004] The above mechanism detects the leakage point by adjusting the position of the probe and emitting signals of different frequencies during detection. However, in actual use, the probe needs to accurately emit and receive signals. Therefore, the probe needs to be protected when not in use to avoid damage caused by impact and affect the service life of the probe. UTILITY MODEL CONTENTS

[0008] The outer side of the handle is sleeved with an anti-skid pad, and the outer side of the anti-skid pad is clamped with an anti-skid mechanism for increasing the anti-skid performance of the handle in use.

[0009] Further, one side of the protective shell is fixedly connected with a buffer pad, and the inner side of the buffer pad is in contact with the outer side of the probe head.

[0010] Further, one side of the protective shell is fixedly connected with four buffer springs, one side of the buffer spring is fixedly connected with a connecting plate, and one side of the connecting plate is fixedly connected with a rubber layer.

[0011] Further, the anti-skid mechanism comprises a clamping block, and the clamping block is fixedly connected to the outer side of the handle, and the inner side of the anti-skid pad is provided with a clamping groove matched with the clamping block.

[0012] Further, the outer side of the anti-skid pad is fixedly connected with anti-skid protrusions, and the anti-skid protrusions are distributed at equal intervals on the outer side of the anti-skid pad.

[0013] Further, the inner side of the fixed pipe is provided with a sealing mechanism for increasing the sealing performance when the connecting pipe and the fixed pipe are connected, the inner side of the fixed pipe is provided with a first air bag, one side of the first air bag is fixedly connected with a second air bag through a hose, and the inner side of the second air bag is in close contact with the outer side of the connecting pipe.

[0014] Further, the inner diameter of the first air bag is smaller than the inner diameter of the second air bag, and the inner diameter of the second air bag is larger than the outer diameter of the connecting pipe.

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] 1. By sleeving the protective shell on the outer side of the mounting plate and screwing, the mounting plate and the protective shell are threadedly connected, so that the protective shell protects the outer side of the probe head, the material of the protective shell can be acrylic, thereby better protection is achieved, and the buffer pad can protect the bottom end of the probe head after the protective shell is screwed, so that excessive screwing and extrusion damage are avoided.

[0017] Further, when the probe head is accidentally dropped, the buffer spring and the damper in the buffer spring can buffer the impact force generated when falling, thereby protecting the probe head, and the rubber layer can also protect the probe head when impacted.

[0018] Further, by inserting the connecting pipe into the inside of the fixed pipe, the connecting pipe will extrude the first air bag inside the fixed pipe, so that the gas inside the first air bag enters the inside of the second air bag through the hose, so that the second air bag can fill the gap between the connecting pipe and the fixed pipe, thereby making the connection between the connecting pipe and the fixed pipe more tight, and facilitating better protection of the connection between the connecting pipe and the fixed pipe.

[0019] 2. By moving the anti-skid pad from below the handle along the direction of the clamping block upwards, the clamping block is clamped with the clamping groove, and at the same time the anti-skid pad is sleeved on the outside of the handle, thereby playing a role of anti-skid holding during use. The clamping of the clamping groove and the clamping block enables the anti-skid pad to be installed at different positions according to different holding habits. When the clamping block is clamped with the clamping groove at different positions, the position of the anti-skid pad installed on the handle changes, thereby facilitating adjustment according to the use habits of different workers.

[0020] Further, the anti-skid protrusions are distributed on the outside of the anti-skid pad, thereby playing a role of anti-skid holding during holding. The anti-skid protrusions increase the contact area with the palm of the user when holding the anti-skid pad, thereby increasing the anti-skid performance during holding.

[0033] Embodiment two:

[0034] As shown in the technical solutions in the technical solutions shown in Figure 1 ,Figure 2 and Figure 4 The technical solution shown addresses the problem of the underground pipeline leak detector with protective function by disclosing an anti-slip mechanism. An anti-slip pad 15 is fitted on the outer side of the handle 2, and an anti-slip mechanism that increases the anti-slip performance of the handle 2 during use is engaged on the outer side of the anti-slip pad 15. The anti-slip mechanism includes a locking block 17, which is fixedly connected to the outer side of the handle 2. A slot 16 matching the locking block 17 is opened on the inner side of the anti-slip pad 15.

The inner diameter of the first airbag 12 is smaller than the inner diameter of the second airbag 14, and the inner diameter of the second airbag 14 is larger than the outer diameter of the connecting pipe 3.

[0038] In this example, by inserting the connecting tube 3 into the fixed tube 11, the connecting tube 3 compresses the first airbag 12 inside the fixed tube 11, thereby allowing the gas inside the first airbag 12 to enter the second airbag 14 through the hose 13. This allows the second airbag 14 to fill the gap between the connecting tube 3 and the fixed tube 11, making the connection between the connecting tube 3 and the fixed tube 11 tighter and providing better protection for the connection between the connecting tube 3 and the fixed tube 11.
